To constrain the parameter spaces of the cosmological scenarios described above, we have used the publicly available Markov Chain Monte Carlo code CosmoMC [1]}, [2]} (see http://cosmologist.info/cosmomc/), which supports the Planck 2018 likelihood [3]} and additionally has a convergence diagnostic following the Gelman-Rubin statistics [4]}. We adopt on the parameters discussed above the flat priors listed in tab.priors.
